No need to comment. Posted for mentoring group to illustrate structure/detail in b&w. Probably obvious, but these are the same images, processed exactly the same way (using Nik Suite Silver Efex), with the only difference in the slider for structure. Top is low, bottom is high.
This is really a great post for comparison. It seems like the "structure" slider changes mainly the contrast and sharpness of the image...quite a handy tool!
I know just in Camera Raw I am amazed daily what I can do. I think I'll post a picture sooc but then I have to tweak it abit and just love how it comes out. Sometime I may get so of this other processing programs. You certainly inspire me to want to.
